Special Issue Information

Air pollution is a major issue in urban areas. High population density is related to excess anthropogenic emissions, impacting upon the environment and health. According to the World Health Organization (WHO), each year approximately 7 million human deaths are attributed to exposure to ambient air pollution. To perform air quality monitoring in urban areas, there is a need to measure the pollution with high resolution. Indeed, highly accurate and reliable air quality monitoring stations have been established to continuously monitor air quality. However, these monitoring stations are expensive and complex to establish, operate, and maintain. Therefore, it is not feasible to deploy these stations massively in urban areas. Alternatively, the dense deployment of low-cost air quality sensors in urban areas enables the detection of the pollution hot spots in real-time. Low-cost air quality sensors are also beneficial to be deployed indoors, where official monitoring stations are not able to perform measurements.

Due to the impact of air pollution on human health, as well as the increasing popularity of low-cost air quality sensors, this Special Issue aims to publish new research and reviews to assess and examine the adverse health effects via the assimilation of data from low-cost air quality sensors both indoors and outdoors. The scope of this Special Issue also includes Internet of things technology and several data science methods, such as data mining and machine learning for processing and analyzing air quality data for investigating health exposure. We are also interested in air quality data fusion and its association to human health as well as environmental epidemiology.

Use of a multi-sensor approach can provide citizens with holistic insights into the air quality of their immediate surroundings and their personal exposure to urban stressors. Our work, as part of the ICARUS H2020 project, which included over 600 participants from seven European cities, discusses the data fusion and harmonization of a diverse set of multi-sensor data streams to provide a comprehensive and understandable report for participants. Harmonizing the data streams identified issues with the sensor devices and protocols, such as non-uniform timestamps, data gaps, difficult data retrieval from commercial devices, and coarse activity data logging. Our process of data fusion and harmonization allowed us to automate visualizations and reports, and consequently provide each participant with a detailed individualized report. Results showed that a key solution was to streamline the code and speed up the process, which necessitated certain compromises in visualizing the data. A thought-out process of data fusion and harmonization of a diverse set of multi-sensor data streams considerably improved the quality and quantity of distilled data that a research participant received. Though automation considerably accelerated the production of the reports, manual and structured double checks are strongly recommended. Full article

The activity pattern is a significant factor in identifying hotspots of personal exposure to air pollutants, such as PM2.5. However, the recording process of an activity pattern can be annoying to study participants, because they are often asked to bring a diary or a tracking recorder to write or validate their activity patterns when they change their activity profiles. Furthermore, the accuracy of the records of activity patterns can be lower, because people can mistakenly record them. Thus, this paper proposes an idea to overcome these problems and make the whole data-collection process easier and more reliable. Our idea was based on transforming training data using the statistical properties of the children’s personal exposure level to PM2.5, temperature, and relative humidity and applying the properties to a decision tree algorithm for classification of activity patterns. From our final machine-learning modeling processes, we observed that the accuracy for activity-pattern classification was more than 90% in both the training and test data. We believe that our methodology can be used effectively in data-collection tasks and alleviate the annoyance that study participants may feel. Full article
